LIQUID-FUEL BURNER.

' Application .filed May a,

the invention, such as will enable others skilled in the art to which itappertainsto make and use the same. v

Thisinvention relates to new anduset'ul improvements in burners andparticularly to burners for vaporizing and burning liquid fuel, such askerosene.

One object of the invention is to provide a burner which has novel andimproved means for supplying air, for combustion, to the escaping gas,and at the same time to direct the air and gas against the generatorpipes.

Another object is to provide a device of this character wherein the heatfrom the flame of the burning fuel is. absorbed by a porous materialwhich is so arranged as to radiate its heat with the maximum efliciency.

Other objects and advantages will be apparent from the vfollowingdescription when taken in connection with the accompanying drawing.

In the drawing: I t

Figure 1 is a side elevation of a burner made in accordance with theinvention.

Figure 2 is a top plan view of the same.

Figure 3 is a vertical transverse sectional view on the line 3-3 ofFigure 2, showing the gas openings, and the air openings with theirdirecting wings.

Referring particularly. to the accompanying drawing, 10 represents a panhaving its bottom upwardly arched, throughout its length, as shown at11, and secured to the lower face of said bottom are the transverse bars12, which are adapted to rest on the bars of a cook-stove grate, thebars being riveted to the bottom of the pan 10. Extending lon-igitudinally of the pan, and resting in notches 13, in the upper edges 01the ends of the pan, are the side pipe portions 14, of the generator 15,the ends of the pipe portions being connected by the transverse pipes 16and 17, respectively, whereby. a rec- 1922. Serial no. 557,883.

tangular frame isthus formed. Connected tothe pipe 16, in thelowersidethereof, and

extending longitudinally "in parallel, relation to the pipes 14, butbeneath the arched bottom of the pan, is the burner pipe-.18,

the other end of said pipe terminating adj acent the other transversepipe 17', asjclearly seen in the plan view, Figure 2. Connected to-theouter side of the pipe 1'? is a'liquid fuel conductor 19, which conveysfuel to. the generaton and leads from any suitable source, not shown. 7r s "In the pipe 18, adjacent each end, and above a horizontal linedrawn through the pipe, are the gas outlet or burner openings 20, saidopenings being formed by boring,

- from-the outer face of the pipe to a distance approximatelythree-quarters ofthe thick ness of the pipe, and then drilling a verysmall hole 20 in the center of the .bottom' of the thus bored recess'oropening 20. It .will be noted that these openings are disposed in suchposition that the flame which issues therefrom, is directed against theside pipe 14. In the side walls of the arched bottom, above each of theopenings 20, there is formed an opening 21, the upper and lower portionsof the walls thereoitbeing bent outwardly and upwardly toward the sidepipes 14, so that the gas from the openings 20 will pass therethrough,while the air from beneath the pan, will also. pass upwardly throughsaid openings, and mix with the gas, to aid the combustion thereof.

Disposed transversely of the generator, and having their downwardlycurved ends 22, resting on the side pipes 14, are the bars 22, thesaidbars supporting the firebrick -23 thereon. Between the side walls .24,of the fire-pot 25, and the sides of the fire-brick 23, brokenfire-brick pieces 26.

The flames from the openings 20 rise againstthe side pipes 14, heatingsaid pipes so as to cause the vaporization of the liquid fuel whichpasses through them, on the way to the burner pipe, 18, and travels orrises upwardly to heat the fire-brick 28, as well as the brokenfire-brick 26. Theheat absorbed by these bricks, and then radiatedtherefrom, serves to produce a sufliciently high temperature to permitheating of water in the water tank and cooking or baking in the oven, aswell as cooking on the top of the stove. When thebricks have becomeheated to a high temperature, the flow of liquid fuel can be checked,with the consequent saving of fuel.

What is claimed is:

1. A heating device including a pan, an arch in the pan formed withopenings in the sides thereof, outwardly extending air and gas directingwings in the openings, a generator above the arch, a burner disposedbeneath the arch and having openings positioned to discharge flamethrough the air openings, and heat absorbing means'supported on thegenerator.

2; A heating device including a pan having a transversely arched bottomformed with openings in the sides thereof, outwardly extending air andgas directing wings in the openings, a generator supported on the panabove the arched bottom, a burner disposed beneath the arched bottom andhaving openings positioned to discharge flame through the air openings,and heat absori ing and radiating means supported on the generator.

3. A. heating device including a pan, a generator supported on the pan,a burner beneath the pan, the pan having air and gas openings, means forsupporting the pan on a stove grate, transverse bars on the generator, aheat absorbing and radiating member supported on the bars, and brokenheat absorbing and radiating means at the sides of the first heatadsorbing and radiating means.

In testimony whereof, I a'iiix my signature, in the presence of twowitnesses.
